NOW L-Cysteine is a non-essential amino acid that is an important component of hair, nails and the keratin of the skin. L-Cysteine stabilizes protein structure and aids in the formation of collagen, thereby promoting healthy skin, hair and nail texture and elasticity. L-cysteine is considered the most important sulfur-containing amino acid and is found in high amounts in hair and nails. It is not considered an essential amino acid as the body is able to manufacture it from the dietary intake of other amino acid-containing foods (proteins).

L-cysteine helps facilitate the health of the stomach lining and maintain the integrity of the gastrointestinal tract lining. It contains sulfur which is used by the body in many biochemical processes, and it is an important component of glutathione, the body's master antioxidant, and aids the body in eliminating toxins while protecting cells from free-radical damage.

Along with other amino acids, which are often called the building blocks of protein, l-cysteine may play a role in increasing muscle mass in the body. For this reason, they are used as supplements by bodybuilders and other fitness enthusiasts who want to increase their size or strength. L-cysteine is also reported to have benefits for those who suffer from chronic lung or respiratory diseases because it helps to break down and thin mucus in the body. The amino acid may also be taken on a temporary basis when a cold, seasonal allergies, or other illness causes the body to produce more mucous.

L-cysteine is also reported to have digestive benefits, such as protecting the stomach and intestinal lining against damage from certain medications such as aspirin. It may also have antioxidant properties and has been shown to elevate the level of certain antioxidants in the body.

Antioxidants are substances that break down toxins known as free radicals in the body, which are believed to play a role in the development of cancer. Some people who take l-cysteine supplements believe that it helps to stimulate the body’s natural processes for hair growth. In some cases, patients may receive l-cysteine intravenously as part of the treatment for acetaminophen overdose.

L-cysteine is essential for T-cell production and immune system activation. L-cysteine is also a component of human hair (research has shown it can increase hair health and hair diameter) and is a component of the hormone insulin. L-cysteine can also be converted into glucose (for energy production) when blood glucose levels are low and this conversion may enhance athletic endurance and prevent muscle catabolism.

L-cysteine supports the synthesis of the highly antioxidative Glutathione and can also be stored in this chemical form. It therefore plays an important part in detoxification and the resulting protection of several tissues and organs.

According to recent research studies this does not only slow down the natural process of ageing, but also helps in preventing dementia and multiple sclerosis, because both conditions are associated with an accumulation of toxins.

Glutathione also inhibits inflammation and leads to an overall strengthening of the immune system. It also stimulates the productions of so-called Leukotrien, which supports the defensive work of the macrophages, which are key elements in the immune system.

In cases of short falls of Cysteine infections may therefore become more prevalent due to the reduced amount of killer cells. In extreme cases, however, such shortfall can lead to cancer when the immune system is extremely weakened.

L-cysteine is also important in the metabolism of lipids. It plays, for example, a part in building essential fatty acids and therefore enables the production of cell membranes and protective covers of nerve endings. These consist mainly of myelin, a dielectric (electrically insulating) material that forms a layer, the myelin sheath, usually around only the axon of a neuron.

This protects the axon from environmental damage and attacks from free oxidative radicals. In this way L-cysteine has very high preventative potency in helping to prevent major degenerative illnesses such as Parkinson.
